DRAG-SCRAPER.

Specification of Letters Patent.

Patented July 10, 1906.

Application filed October 4,1905. Serial No. 281,309.

To all whom, it may concern:

Be it known that 1, JAMES L. TORBETT, a citizen of the United States,residing at Pleasanton, county of Linn, and State of Kansas, haveinvented certain new and useful 1mprovements in DragScrapers, of whichthe following is a specification.

This invention relates to drag-scrapers The obj eot of the presentinvention is the provision of an improved drag-scraper having meanswhereby the mere raising of the handles will automatically release thescoop and the latter will automatically dump itself as the scraperadvances and thereafter become locked in scraping position.

To carry out the foregoing object, I provide certain improved de viceswhich are set forth fully hereinafter and the novel features thereof arerecited in the appended claims.

In the accompanying drawings, Figure 1 is a perspective, dotted linesshowing the handleframe raised and the scoop starting to dump. Fig. 2 isa bottom view; Fig. 3, enlarged detail views of the automatic lockingmechanism and parts of the scoop, handles, and yoke, illustrating thedifferent positions of the parts.

The yoke to which the horse is hitched is shown at 1, and 2 representsthe handleframe, which is pivoted to the yoke 1 at 3, so as to beadapted to be swung up and down, as desired. The scoop 4 is pivoted onthe pivots 3, so as to be capable of swinging in the handle-frame 2 andyoke 1, said scoop having pins or points 5 on the upper edge of itsback. The side pieces of the handleframe 2 have their inner surfaces cutout or notched at 6 for the free passage of stop-pins 7 on oppositesides of the scoop but the notches 6 are normally covered by slidinggates 8, whose forward ends are pivoted at 9 to the downward extensions10 of the rear ends of the yoke 1. These gates are guided by headed pins11, entered in the handle-frame 2 and passing through slots 12 in thegates. A spring-actuated latch 13, pivoted to the under side of thehandle-frame, is adapted to engage a notched member 14 on the back ofthe scoop and lock the latter against backward turning or reversal.

hen the scraper is in normal condition or at work, the latch 13 is inengagement with member 14 and the gates 8 cover the notches 6, thestop-pins 7 resting against the under sides of said gates 8. lVhen it itdesired to dump the scoop, the operator swings the handle-frame on itspivots 3 to the upright position shown in dotted lines in Fig. 1, and asthe yoke remains in its former position this movement causes anuncovering of the notches 6, as illustrated in Fig. 3. The latch 13causes the scoop to move upwardly with the handle-frame when the latteris raised, thereby causing the toe of the scoop to dig into or engagethe ground, so that when the openings or notches 6 are uncovered thestop-pins 7 are released and pass through notches 6, permitting thescoop to turn upside down as the horse advances, until the pins 5 engagethe ground and cause a complete reversal and dumping of the scoop. Thehandle-frame should be held raised by the operator until the scoop hasreversed, and it should then be brought down to normal position to causethe gates 8 to again cover the notches 6, so that when the scoop comesto normal position the stop-pins 7 will bring up against the lower sideof gates S. Then the scoop reaches normal position, the latch 13reengages member 14. The dumping and relocking of the scoop is entirelyautomatic, save for the mere raising and lowering of the handle-frame bythe operator, which is a very simple and easy operation.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A scraper, comprising a yoke, a handleframe pivoted to the yoke, apivoted reversible scoop, and means for retaining the scoop in normalposition, said means cooperating with the handle-frame and being adaptedfor the release and locking of the scoop by raising and lowering thehandle-frame.

2. A scraper, comprising a yoke, a handleframe pivoted to the yoke, areversible scoop pivoted to the handle-frame, and scoop locking andreleasing means carried by the yoke and coperating with the handle-frameso that raising and lowering the handle-frame unlocks and locks thescoop.

3. A scraper, comprising a yoke, a handleframe pivoted to the yoke, apivoted reversible scoop, and means for locking the scoop, saidmeansbeing pivotally connected to the yoke at a point offset from thepoint of pivoting of the yoke and handle-frame, said looking meanscooperating With said handle frame, whereby raising or lowering thehanpins when the scoop is in normai position but i6 die-frame unlocks orlooks the scoop. disengaged therefrom by raising the handle- 4.
